“I don’t know. It’s not fun. It’s not fun,” Newton told reporters. “It’s really taken the fun out of the game for me. Honestly, it really is because at times I don’t even feel safe and enough is enough.”

Carolina Panthers quarterback Cam Newton spoke directly to not feeling safe during games during his postgame press conference on Sunday. Despite the Panthers' 30-20 victory over the Arizona Cardinals, Newton said the breaking point was when he could have torn his Achilles' tendon. Jeff SinerCharlotte Observer

Newton also said that he planned to talk with NFL commissioner Roger Goodell about his objections.

“I don’t know what I have to do. I showed a lot of frustration today and I apologize to the referee who I was talking to, but I don’t think there is a person that can go through what I go through and still keep their head,” Newton said.

“Hits to the heads are one thing, but when you’re not protected in the pocket, that’s another thing.”
